Mexico (Nuevo León, Tamaulipas, Veracruz, Michoacán, Oaxaca, Chiapas), Guatemala, El Salvador, Costa Rica, Venezuela, Brazil. First record from Venezuela. Biology. Apechthis zapoteca resembles a common vespid, Agelaia (= Stelopolybia) sp. near multipicta (Haliday) (Vespidae), of which it is probably a Müllerian mimic (Gauld 1991). Recorded as parasitoid of Leptophobia aripa (Boisduval) (Lepidoptera: Pieridae) in Guatemala (Gauld et al. 1998). Parasitoid of Sarsina violascens (Herrich- Schäffer) (Lymantriidae) in Brazil (Costa-Lima 1951; Townes & Townes 1966).
